=SUMIFS({QTY produced}, {completed date}, <=TODAY(), {completed date}, >=TODAY(-30), {element}, ([description reference]@row))
This formula is pulling completed dates from another sheet. I am wanting the formula above to only count quantities 30 working days from today's date. Is there a way to modify this formula to include only working days? I think that the sheet is counting weekends at this moment. I updated the properties of the sheet to specify Mon-Fri, but not sure how to implement "WORKDAY" into the formula. Can you please advise?
